Containerized Water Treatment Plants

Lenntech builds water treatment plants inside shipping containers, from complete desalination plants to emergency response units. Every plant leaves our workshop fully piped and wired, ready to connect on site.

Since 1993 we have designed and built water treatment systems for clients in more than 140 countries. Our containerized plants run on islands, in deserts, at remote villages and at emergency sites, treating seawater, brackish water and other sources with varying salinity. The core process is often reverse osmosis (RO), in which semi-permeable membranes remove dissolved salts and contaminants.

Capacity is designed around your needs: a single container for smaller flows, or several containers working together for larger plants.

Why choose a containerized plant?

Compared with a plant built into a plant room on site, a containerized plant offers:

  • Plug and play: connect the inlet, outlet and power, and start up
  • Quick installation: the plant is assembled before delivery
  • Limited civil work: only a foundation for the container
  • Small footprint
  • Easy transport: standard container size
  • Mobility: ideal for construction sites and temporary needs
  • Turnkey delivery: all piping and cabling installed, plus air conditioning where required

A complete installation, not just a container

Containerization covers the complete installation of the plant inside the container:

  • All piping and fittings connected between pumps, pressure vessels, skids and tanks
  • All pumps and instruments cabled and wired to the main control cabinet

Every plant is fully designed in 3D before construction. The chemical room is separated from the main equipment room.

Container equipment

We deliver our systems in insulated 20 or 40 ft containers. The container is fitted with:

  • Side doors for access to the equipment
  • One inlet/outlet terminal point
  • A roof hatch
  • Floor drainage

Options on request:

  • Sun roof to limit the inside temperature in extreme climates
  • Air conditioning with a split unit; the outdoor unit is placed next to the container

Larger plants are split over several containers that are connected on site.

Pre-treatment tailored to your water

Each plant is custom designed, and the design depends on your water quality. Reverse osmosis units often need pre-treatment for:

  • Suspended solids
  • TOC, COD/BOD and hydrocarbons
  • Iron and manganese
  • Hardness

Lenntech supplies all pre-treatment your RO needs, based on your water analysis and process requirements. Besides desalination, we also containerize other treatment lines, such as ultrafiltration, softening and wastewater reuse.
